About This Experience

The Great Barrier Reef is the largest coral reef system on Earth, stretching over 2,300 kilometres along Australia's northeast coast. From Cairns, day trips take you out to Green Island or the outer reef where the coral formations and marine life are breathtaking.

What to Expect

Whether you choose snorkelling or scuba diving, the underwater world reveals an explosion of colour — vivid corals, tropical fish, sea turtles, and if you're lucky, reef sharks gliding by. Glass-bottom boats are available for those who prefer to stay dry.

Practical Tips

• Book early during peak season (June–October)
• Reef-safe sunscreen is essential — protect the corals
• Motion sickness tablets help on the boat ride out
• Underwater cameras are a must
